Fish McBites are “crispy, tender pieces of poppable flaky wild-caught Alaskan Pollock,” according to McDonald’s. The company says the fish are sourced from a Marine Stewardship Council (MSC) certified sustainable fishery. Like the Chicken McBites, Fish McBites are available in three sizes – Snack (3 ounces), Regular (5 ounces) and Shareable (10 ounces).

McDonald’s is even offering a Fish McBites Happy Meal.

The introduction of Fish McBites comes as McDonald’s celebrates the 50th anniversary of the Filet-O-Fish fish sandwich. Fish McBites will be available through March at McDonald’s restaurants.
